Support

Due to the rapid changes being made in the React Native ecosystem, we are not officially going to support this module on anything but the latest version of React Native. The current supported version is indicated on the React Native badge at the top of this README. If it's out of date, we encourage you to submit a pull request!

Usage

Linking the Library

In order to use Safari View, you must first link the library your project. There's excellent documentation on how to do this in the React Native Docs.

Displaying the Safari View

Once you've linked the library, you'll want to make it available to your app by requiring it:

var SafariView = require('react-native-safari-view');

Displaying the Safari View is as simple as calling:

SafariView.show({
  url: 'https://github.com/naoufal'
});

URL Change Notifications

There isn't an API for retrieving URL changes provided by SFSafariViewController or its delegate in iOS, so there's no way to know where the user is navigating to. However, it is possible to get a notification when the Safari View navigates to an URL scheme specified by your app (e.g. your-app-name://). This is especially useful for implementing callback oriented flows such as in OAuth2 / OpenID Connect.

To get URL notifications for your URL scheme you'll need to:

1. Register an URL scheme in your Xcode Project
2. Make sure you've set up Linking in your react-native project.
3. Listen for URL changes in your react-native code (i.e. Linking.addEventListener('url', eventHandler));

Example

Using Safari View in your app will usually look like this:

import React, { Component } from "react";
import SafariView from "react-native-safari-view";

class YourComponent extends Component {
  constructor(props) {
    super(props);
  }

  _pressHandler() {
    SafariView.isAvailable()
      .then(SafariView.show({
        url: "https://github.com/naoufal"
      }))
      .catch(error => {
        // Fallback WebView code for iOS 8 and earlier
      });
  }

  render() {
    return (
      <View>
        ...
        <Button onPress={this._pressHandler}>
          Show Safari View
        </Button>
      </View>
    );
  }
}
